Two Nerds have spent the last few episodes discussing time travel, repeating day, or otherwise timey-wimey narratives. Adjacent to that (and often overlapping) are stories that explore parallel worlds. In this outing, we discussthe movies Sliding Doors and Another Earth, and touch on a series called Counterpart. Sliding Doors is a rom-com from 1999, and Another Earth a melancholy indie movie from 2005. Counterpart is something like a spy thriller, with two alternate Earths in a cold war of sorts.
